Unknown devices issue

I installed Windows 8.1, but my devices manager is showing 5 device errors under "Other devices"
They are as follows:
Unknown Device ( Location: on Microsoft ACPI-Compliant System‎)
ACPI\VEN_HPQ&DEV_6001
ACPI\HPQ6001
*HPQ6001
Unknown Device ( Location: on Microsoft ACPI-Compliant System‎)

yes three of them are identical, and I don't know why.
Anyone know how I can udpdate the drivers for these devices?
Thanks

Satellite P775-S7320 Unknown Device issue

Unknown Device
Device Type:     Universal Serial Bus controllers
Manufacturer:    (Standard USB Host Controller)
Location:            Port_#0002.Hub_#0004
Windows has stopped this device because it has reported problems. (Code 43)
I'm trying to figure out what this device is before I open the laptop and start poking around.
Any info would help, thanks in advance.

I can remove all external USB devices and the issue still exists. The internal webcam is USB and working fine, so is the toutchpad but also working fine. I suspect another internal USB device, but I have no idea what else is USB. I don't use the WiDi and wondering if that is considered an internal USB connected device.

IPhone "Unknown Device" issue

I picked up my iPhone 4 this afternoon and it had gone to a white screen and seemed stuck there. It would not shut down. It would not come back to life. I did a cold reset and then connected to iTunes to restore my saved setup. When I power up the iPhone, I get the usual new phone sequence up to and past the point at which I identify the wi-fi network to which I want to connect. Then the train jumps the tracks. The on-screen message in iTunes is "Unknown Device." The phone displays an error message, although now I cannot recall exactly what it says. You pros got any recommendations on this?

Firewire Bus/Unknown Device?

Hello to all. I just picked up a New 2.3GHz Power Mac and when I was checking the System Profiler in the Firewire section it reads Firewire Bus
Unknown Device
FireWire Bus:
Maximum Speed: Up to 800 Mb/sec
Unknown Device:
Manufacturer: Unknown
Model: Unknown Device
Maximum Speed: Up to 400 Mb/sec
Connection Speed: Up to 400 Mb/sec
The funny thing is I have nothing plugged into any of the Firewire Ports! The other strange thing is I have a 20 inch Cinema Display (which has a USB and Firewire Hub built into the back of the display) and If I plug that Firewire plug into the Computer I get a Duplicate reading of the info above (looks like this):
FireWire Bus:
Maximum Speed: Up to 800 Mb/sec
Unknown Device:
Manufacturer: Unknown
Model: Unknown Device
Maximum Speed: Up to 400 Mb/sec
Connection Speed: Up to 400 Mb/sec
Unknown Device:
Manufacturer: Unknown
Model: Unknown Device
Maximum Speed: Up to 400 Mb/sec
Connection Speed: Up to 400 Mb/sec
I called Apple and They had me run every test under the sun. As a last resort They had me erase the Drive and do a reinstall of just the basic Apple Software and this is what I ended up with. I thought maybe one of you kind folks might have some idea of what the **** is going on.
Thanks

Thanks so much for your replies. So what is the technical explaination for this because I have been on the phone with Apple for hours over the last 2 days send them all sorts of system data. I even mentioned the fact that I have seen postings listed on this forum with other people with the same Unkown Error issue happening to there Dual Core machines and the people I have spoken with at Apple are acting like the have never heard of this before. I only noticed this Unknown Device thing because I am in the Audio Recording business and I am having a problem with my Digidesign DIGI002 interface giving me this slight distortion problem coming out of the 002 unit. But this was happening when I had the 002 connected to my Powerbook 17inch 1.33. I figured it was some type of software issue but now I'm checking into the 002 as the culprit! And the people down at Digidesign have never heard about this Unknown Device Issue as well and think that could be messing up the 002 but I do not have this Unknown Device thing going on with my Powerbook. So I'm stumped!
Thanks again!

Fix for "Unknown Device" when the iPod is connected

After a few long nights, a few headaches, hours and hours of reading, thinking and many toasted sandwiches, I finally found the problem to my iPod not loading. Putting together information I had read here and at many other sites I had a brainwave... and sure enough it worked. I figure this may be helpful to many other iPod users, so... here I am posting my solution. Note though, this wont help all users, but I know I wasnt alone with this issue, and this just might help someone.
Ill list the issue I was having (this may help other people identify their issue to mine) was that the iPod failed to work on windows, and threw a fit when plugged in. Windows did too, iTunes would lock up and the iPod software failed to recognise that an iPod was connected. The iPod had worked on an older PCs before, but it failed to work on my new homebuilt PC. When I first connected the iPod it began to work, transferring and updating.. but then it unexpectedly disconnected the iPod.. and mentioned something to do with an I/O error, the iPod had to be disconnected and it also mentioned something to do with a timeout error and dataloss (or as it put it Data has been destroyed. Thats always a pleasant message to read). Suddenly, half the music on my iPod wouldn't play, it skipped songs until it found a song it would play... really annoying. I tried to format the iPod using the iPod software... buuut it told me that it wasnt an iPod that was connected (Funny that... lol). After the first iPod crash, it would react differently when connected. It would once again pop up with the Found new hardware bubble, Apple iPod..., Disk Drive... ... then iTunes loads... then iTunes freezes... then the iPod disconnects 2 mins later, then iTunes unfreezes. THEN the next time the iPod is connected, it would say it was an Unknown device, and that it has Malfunctioned.
It seems that, oddly enough, my iPod (I own the 30gig iPod Photo) does not like USB 2.0... Im thinking that it must not support some of the device commands the PC is sending to it... Weird though, because on other USB 2.0 PCs it worked fine. (I got the best results out of Dell PCs...). IF USB 2.0 is disabled and slows to USB 1.1 the iPod works a charm... jumped up without an issue in the world. To disable USB 2.0, jump into BIOS as your pc is in its POST stages... this being, when the PC is first turned on and presents a message such as Press DEL to enter setup (or something similar), do so. Then refer to your manual on how to disable USB 2.0, if possible. Apply the changes and reboot. Be sure not to mess around with other settings, it is very easy to mess up your computer if you change settings you are not familiar with.
Other solutions would be to run the iPod via Firewire... if you can get a cable. Run along to your local mac store and see if they have one in stock. Ill get back on here to post if using Firewire solved the issue later.
Perhaps a motherboard BIOS upgrade, or newer drivers could resolve the issue. This may explain to some people why their iPod stopped working overnight after working fine for so long, maybe an update of the sort was installed. Apparently my motherboard already has an update, so Ill test that sometime and post my results as I investigate further, but as for now Im just happy my iPod is working, even if it is taking ages to transfer (25 gigs of music takes awhile over USB 1.1 lol...).
Also, I might add that my motherboard is an ASUS P5P800 with the Intel 865PE chipset. It could be an interesting pattern seeing which motherboards do not seem to be compatible with the iPod at USB 2.0 speeds.
As long as this post was I hope that someone gets some use out of it. Ill post further findings as I investigate this matter further.
Happy iPodding!

hi Jazza!
the best explanation for this that i've seen is that there can be power drain problems in USB 2.0. drop below 500 mA running through the port and everything goes to pot. this may well explain why switching back to USB 1.1 sometimes works like a charm, and also explains why it's important to have the ipod plugged into a high powered USB port rather than a low power port.
i've seen a confirmed case of a USB connection going west after a scanner got plugged into the beast in question ... periodically i see other reports along these lines, too.

USB Ports - Mass Storage Devices - Unknown Device

Model: Satellite A135-S2276
OS: Vista
I recently tried plugging in my media card reader that I've had for several years now and has worked many dozens of times. Windows responded with an 'Unknown Device' response. I thought this was odd, so I changed and tried each USB port. To no avail the device wasn't recognized. I tried it in another computer and it worked fine.
I began to try two other mass storage devices that I know used to work, up until recently, on the laptop. Both now are 'Unknown Devices'. I now have a strong feeling that someting was wrong with windows vista. So I search around and find methods to force the driver (inf) cache to reset which should reload any corrupted drivers. Tried many methods, nothing worked, same results. I saw that Vista Service Pack 2 just came out, I installed that hoping that it would fix. Nope.
I gave up on it being a software issue after I did a fresh reinstall of the OS and with the base OS with no other software installed same results.
Is there a way to diagnose if the USB is malfunctioning from a hardware standpoint? Is it possible the USB, even thought windows recognizes it, is dead on the motherobard? If so, how do I get this fixed? Motherboard replacement?
Help!!

It sounds like it is working enough that it can recognize that soemthign is plugged into it.
You say you did a fresh install of Windows. Did you use the recovery disk or a retail Windows copy. If oyu didn't use the recovery disk then maybe you are missing a driver. Best woudl be to use the recovery disk. If a USB mouse doesn't work after that then the hardware has an issue. Assuming the BIOS is OK.

IBook won't load Firewire drive; "unknown device"

That's the summation via System Profiler. It's a SmartDisk Firelite enclosure but I swapped the old 40 GB drive that failed for a new Seagate Momentus 80 GB drive. My G4 dualie recognizes the new SmartDisk setup fine. It loads immediately and I was able to access via all the utilities. Transfers work well.
But on the 1.33 iBook the green light appears on the SmartDisk enclosure, but no threat of loading. Only System Profiler identifies something, "unknown device" with 400 capability. When I remove the firewire cable, System Profiler doesn't see anything.
I had no trouble with the SmartDisk prior to the old drive failing. It worked perfectly on the iBook. My firewire port appears to be okay, since I tried Target Disk Mode with the two computers and it worked well.
Any suggestions would be greatly appreciated. I Googled and found many issues of "unknown device" related to firewire drives, but none that seemed to precisely fit this case, a drive that was recognized on one computer but not another. Both are running 10.4.11.

I'm still baffled but tonight I found an acceptable alternative, a Macally 250 Firewire/USB enclosure that I had in my closet but never used previously. The Seagate drive loads on both the dualie and iBook using that enclosure, which is bulkier than the SmartDisk but right now I don't really care.

IPod appearing in Device Manager as unknown device

Hi, I'm currently using an iPod Nano 4th Gen. and it is appearing in Device Manager as an unknown device. I found this out after the error message "USB device not recognised" or something, and followed instructions. I'm currently clueless on what to do. My OS is Windows 8. When I go into properties of the unknown device (iPod) the device status is: Windows has stopped this device because it has reported problems. (Code 43). And in details, I get: USB\DEVICE_DESCRIPTOR_FAILURE
If you need any more information to help me, please do not hesitate to request it. I just really would like this issue to be solved. Thank you in advance.

Thank you for the update, passionflower
I think next would be a good idea to shutdown the computer, and disconnect everything from it. Let it sit for a minute or two, then plug it all back up and turn the computer on, then try again.
Next I would start troubleshooting the USB ports on the computer. I would start with this troubleshooting.
On the Start menu, click Control Panel.
Double-click the System icon.
Click the Hardware tab.
Click Device Manager.
Scroll down the list of devices to the Universal Serial Bus controllers
Click the plus icon next to the Universal Serial Bus controllers.
Double-click one of the indented USB Root Hub entries.
Click the Power Management tab.
Deselect the "Allow the computer to turn off this device to save power" option.
Click the OK button at the bottom of the window.
Restart the computer.
From: iPod not recognized when connected to Windows laptop over USB
http://support.apple.com/kb/TS1401
And then this troubleshooting
Plug the device directly into a high-power USB 2.0 port on the computer. If possible, use a USB port on the back of the computer.
Avoid plugging the device into a keyboard, display, or standalone hub. The USB ports on these accessories may be low-power or only offer USB 1.x connections.
If you are using an accessory, remove the accessory and connect the device to the computer using only the Apple 30-pin to USB Cable or Lightning to USB Cable.
If you have access to additional Apple 30-pin to USB Cable or Lightning to USB Cables, try testing with another if the first one doesn't work.
Restart your computer and device. To restart your device:
Hold the power button until "slide to power off" appears. Slide to power off your device. When it is off, press the Sleep/Wake button to turn it back on.
Disconnect all USB devices from your computer, except for your keyboard and mouse. Then reconnect the iOS device. If the issue is resolved, reconnect other USB devices, testing after each connection.
From: iOS: Troubleshooting USB connection
http://support.apple.com/kb/TS1286
If you have another computer you can also test the iPod Nano there to help isolate whether the issue is with the iPod or the computer.
And just in case the issue is still not resolved, I want to thank you for using the Apple Support Community. Due to the nature of your issue you may find more information by using another one of Apple's support resources - https://expresslane.apple.com/GetproductgroupList.action.
All the very best,

Hi:
You may need to reinstall the graphics driver, but I think it is the same one you have now. It is from 2012 and so all they did was say it was good for W8.1 too.
